Your firm's client is a devout Jehovah's Witness, and he recently moved from New Jersey to the District of Columbia. As part of his religion, the client must spread the principles of his religion to the public. When he lived in New Jersey, he had previously paid for a small banner advertisement that was displayed on a public bus in Newark, New Jersey, that warned passengers of the end of the world. Now that your client is living in the District of Columbia, he would like to place a similar advertisement on the public buses in the District of Columbia. Please locate the applicable District of Columbia law to determine whether your firm's client can place such an advertisement in the District of Columbia
